North East Chapter – Irish Woodturners Guild

 

  November 2013

 

Pat Walsh, Dublin Chapter, was our guest for November – incorporating a variety of techniques with intrigue and fascination into his demonstration. His first project was an upright flamed Beech bowl 8”x 3” with a return curve at the top blended into the wall of the bowl, before applying texture and colour. The outside was shaped and finished with a wood chisel which was converted to a negative rake scraper, operated at centre height at 90 degrees. It should be recognized that Negative Rake scrapers need to be re-sharpened every 20 seconds, or if using a Cabinet Scraper sharpen with a diamond file.

Next, the texture was applied using a Sorby texturing tool at centre height presented at 45 degrees and working on the bevel with a pulling motion, with a textured rim to match.  Two important points- close grain woods are best for texturing, and secondly, the texture applied will depend on the speed of the lathe, and the speed of pass, and angle of presentation of the tool.  Clean off fibers with blow torch and brush off with suede brush, and finish cleaning with a nylon brush fitted in a drill, before applying cellulose sanding sealer. 

 

Colouring starts with a light spraying of matt black car paint which may be dried with a hair dryer.  Repeat the process as often as necessary.  If using acrylic paint, remember that this type of paint dries from the outside to inside.  Next, apply an oil based pastel colouring stick to the high points of the texture.  Again, the results of the application depends on lathe speed and speed of movement of application.  Seal with acrylic satin lacquer.  Reverse chuck and turn inside of bowl.  After sanding, finish with two coats of spray acrylic sanding sealer.  Leave overnight before applying burnishing cream with lathe stopped.  Turn on lathe and apply more cream.  Burnish with a clean cloth at high speed for a food safe high sheen finish. 

 

His second project produced spectacular results – starting with a prepared bowl mounted on its spigot, the outside of the bowl and the rim was sprayed with black car paint and dried, and a second coat applied.  Next, a fishnet stocking was fitted over the bowl and secured into position.  Lightly overspray with white paint and dry, repeating this process 3 times.  Seal with clear lacquer spray.  Thanks Pat for a most informative demonstration.
